PHILADELPHIA,  April  11,  1870. 

On  retiring  from  the  business  which  I  established  in  1853,  and  h?,ve  been 
conducting  at  No.  924  Chestnut  Street  since  that  year,  it  gives  me  pleasure 
to  recbmmend  to  my  friends  and  former  patrons,  my  successors,  and  solicit 
for  them  a  continuance  of  the  favors  so  freely  bestowed  upon  myself. 

The  present  firm  propose  dividing  their  business  into  three  departments, 
each  partner  giving  one  of  those  departments  his  special  care  and  attention. 

SAMUEL  L.  Fox,  my  former  partner,  will  devote  himself  to  the  Mathe- 
matical Department,  which  will  comprise  Drawing  Instruments,  of  every 
description,  Surveying  Compasses,  Engineer's  Transits  and  Levels,  Surveying 
Chains,  Tape  Measures,  Drawing  Papers,  and  materials  of  all  kinds  used  by 
engineers  and  draughtsmen. 

JESSE  S.  CHEYNEY,  formerly  Principal  of  Friends'  Select  School,  in  this 
city,  will  take  the  Department  of  Philosophy,  which  will  comprise  Magic 
Lanterns,  Oxy-Calcium  and  Oxy-Hydrogen  Stereoscopticons,  with  Pictures 
and  Illustrations  from  all  countries  and  upon  all  scientific  subjects;  Ther- 
mometers, Barometers,  Globes,  Air  Pumps,  Electric  Machines,  Magnetic 
Apparatus,  &c.,  &c. 

WILLIAM  H.  WALMSLEY,  well  known  throughout  the  country  as  a 
Microscopist,  and  also  a  preparer  of  Microscopic  Specimens,  will  take  the 
Department  of  Optics,  which  will  comprise  Spectacles,  Microscopes,  Micro- 
scopic Objects  and  Accessories,  Opera  Glasses,  Spy  Glasses,  Telescopes, 
Ophthalmoscopes,  &c.,  &c. 

The  new  firm  will  continue  to  issue  Priced  and  Illustrated  Catalogues  as 
follows: — Part  1st.  MATHEMATICS;  Part  2d.  OPTICS;  Part  3d.  MAGIC 
LANTERNS  AND  STEREOPTICONS  ;  Part  4th.  PHILOSOPHICAL  INSTRUMENTS. 

Care  will  be  taken  in  each  department  of  the  business  that  the  instru- 
ments manufactured  by  the  firm  shall  be  well  made,  and  accurate  for  the 
purposes  intended;  and  that  all  new  instruments  and  improvements,  of  both 
European  and  American  manufacture,  shall  be  introduced  with  as  little  delay 
as  possible.

ACHROMATIC!  OBJECT-GLASSES  for  SPY-GLASSES  ajid  TELESCOPES. 

Achromatic  lenses  are  formed  by  a  combination  of  a  double  convex  lens 
of  crown  glass  and  a  plano-concave  or  a  concavo-convex 
lens  of  flint  glass.  The  advantages  of  a  lens  formed  in  this 
manner  are  freedom  from  spherical  aberration  or  distortion, 
and  the  rays  of  light  are  not  decomposed  into  the  primary 
1225.  colors ;  in  other  words,  the  light  passes  through  the  lens 

and  suffers  no  change  thereby.

SPECTACLES  AND  EYE-GLASSES. 

HINTS  AS  TO  THEIR  SELECTION. 

To  select  Spectacles  for  improving  the  Sight  when  Age  is  the  Cause  of  Failure. 

At  the  age  of  forty,  most  ladies  begin  to  experience  some  difficulty  in  threading  a 
•fine  needle  and  reading  very  fine  print,  but  gentlemen  do  not  notice  this  change  until 
about  the  age  of  fifty.  These  ages  do  not  hold  good  in  all  cases,  but  as  an  average 
they  can  be  relied  upon. 

Among  the  indications  that  the  eyes  are  beginning  to  be  impaired  by  age,  and 
that  spectacles  are  required,  are,  the  necessity  of  putting  a  book  farther  from  the 
eyes  than  a  natural  distance  in  order  to  read  fine  print  distinctly ;  a  greater  care  to 
Lave  a  strong  light  upon  the  reading  or  sewing;  as,  for  instance,  going  close  under 
the  window  or  holding  the  light  between  the  eyes  and  the  reading;  on  looking  at  a 
near  object,  in  a  short  time  it  becomes  confused  and  appears  to  have  a  kind  of  a  mist 
before  it,  and  the  letters  of  a  book  run  one  into  another  or  appear  double,  and  after  a 
little  use  the  eyes  have  an  over-taxed  wearied  look. 

In  selecting  Spectacles  to  remedy  these  defects  of  vision,  it  is  desirable  to  consult  an 
experienced  Optician,  and  with  his  advice  and  assistance  to  procure  those  best  suited 
to  the  condition  of  the  eye.  But  in  case  an  Optician  is  not  readily  accessible,  persons 
•wanting  Spectacles,  instead  of  picking  up  and  using  any  kind  which  may  happen  to  be 
at  hand,  regardless  of  the  power  or  quality  of  the  glasses,  would  do  well  to  send  to 
us  for  a  pair ;  and  if  the  following  data  is  carefully  given  us,  we  will  have  no  difficulty 
in  sending  Spectacles  to  suit  the  sight:  — The  age  of  the  person;  and  state,  if  lady  or 
gentleman,  whether  spectacles  have  been  worn;  if  not,  give  the  number  of  inches  — 
Tery  small  printing  must  be  held  from  the  eyes  in  order  to  read  it  distinctly  in  a  good 
light  —  and  send  a  sample  of  the  printing:  but  if  spectacles  have  been  worn,  send  a 
glass  or  piece  of  a  glas"s  from  the  Spectacles  last  worn ;  state  the  age  and  sex  of  the 
person;  how  long  the  last  pair  of  Spectacles  had  been  used,  and  at  what  number  of 
inches  from  the  eyes  with  these  Spectacles  on  very  small  printing  must  be  held  in 
order  to  see  it  distinctly,  and  send  sample  of  the  printing. 

Persons,  after  having  used  Spectacles  for  ten  or  twelve  years  to  assist  them  in  read- 
ing, begin  to  notice  a  change  in  their  sight  with  regard  to  distant  objects,  a  little 
want  of  clearness.  When  Spectacles  are  wanted  to  remedy  this  defect,  if  a  glass  from 
a  pair  of  Spectacles  which  suits  for  reading  small  printing  is  sent  us,  we  can  send  a 
pair  of  Spectacles  that  will  correct  the  defect,  and  give  clear  vision  for  distant  seeing. 

To  select  Spectacles  for  Near-  or  Short  -  Sighted  Persons. 

Near-sighted  persons,  or  those  who  do  not  wear  glasses  to  assist  them  in  reading, 
yet  are  unable  to  see  distant  objects  clearly,  in  order  to  have  the  proper1  glasses  sent 
them,  should  give  us  the  number  of  inches  they  are  obliged  to  hold  very  small  print- 
ing from  their  eyes,  and  send  sample  of  the  printing. 

Colored  glasses  —  blue,  green,  and  smoke  —  may  be  worn  to  protect  the  eyes  from 
intensely  bright  light,  such  as  sunshine,  or  blazing  fire;  but  it  is  not  advisable  to  use 
them  for  reading  or  working.  The  habitual  using  of  them,  where  there  is  only  a 
moderate  light,  is  found  to  have  an  injurious  effect  in  rendering  the  eyes  too  sensitive. 

Spectacles  can  be  transmitted  through  the  mail  with  safety  to  and  from  us.  The 
postage  on  a  single  pair  is  nine  cents. 

All  orders  for  Spectacles  will  receive  our  prompt  and  careful  attention.  And  if 
those  sent  are  not  found  to  be  quite  right,  they  will  be  exchanged  for  others  without 
additional  cost.  In  ordering  Spectacles,  it  will  only  be  necessary  to  give  the  catalogue 
number  of  the  kind  wanted  and  the  information  about  the  sight  before  alluded  to.

TO  DEALERS. 

The  prices  given  on  pages  5  to  14,  for  Spectacles,  Eye-Glasses,  &c.,  are  our  lowest 
retail  prices.  Dealers  who  buy  Spectacles  to  retail  again,  will  find  our  prices  by  the 
dozen  very  low  indeed,  and  they  can  always  have  the  dozens  made  up  of  any  Sights 
they  may  happen  to  be  in  want  of;  the  advantage  of  which  is  that  they  will  never  get 
too  many  of  any  one  number,  while  they  have  none  of  some  very  important  numbers. 
We  have  Steel  Spectacles,  from  $1  50  per  dozen  to  $25  per  dozen.  Eye-glasses,  from 
$3  50  to  $20  per  dozen.

GKAPHOSCOPES, 


1487. 

These  new,  beautiful,  and  extremely  useful  instruments  are  growing  steadily  in 
public  favor,  so  that  of  late  it  has  been  almost  impossible  to  meet  the  demand  for 
them.  We  have,  however,  made  arrangements  with  two  eminent  foreign  manufac- 
turers, by  which,  in  addition  to  our  own  make,  we  shall  be  enabled  to  keep  all  sizes 
in  stock,  and  thus  fill  orders  promptly.  Combining  a  perfect  stereoscope  with  a  large 
lens  for  viewing  single  photographs,  and  engravings  of  almost  any  size,  so  constructed 
as  to  give  a  stereoscopic  appearance  to  them,  the  graphoscope  realizes  a  want  often 
felt  but  never  before  attained,  whilst  its  beautiful  proportions  and  elegant  finish 
make  it  a  handsome  addition  to  the  furniture  of  the  library  or  drawing-room.

THE  MICROSCOPE. 


Within  the  last  few  years,  the  microscope  has  become  so  firmly  rooted  among  us, 
that  little  need  be  said  in  its  praise.  The  time  has  long  passed  away  when  it  was 
Tield  in  no  higher  estimation  than  an  ingenious  toy ;  but  it  is  now  acknowledged  that 
no  one  can  attain  even  a  moderate  knowledge  of  any  physical  science  without  a  con- 
siderable acquaintance  with  the  microscope  and  the  marvellous  phenomena  which  it 
reveals.  The  geologist,  the  chemist,  the  mineralogist,  the  anatomist,  or  the  botanist, 
all  find  the  microscope  a  useful  companion  and  indispensable  aid  in  their  interesting 
and  all-absorbing  researches,  and,  with  every  improvement  in  its  construction,  have 
discovered  a  corresponding  enlargement  and  enlightenment  of  the  field  displayed  by 
the  particular  science  which  they  cultivate. 

But  even  to  those  who  aspire  to  no  scientific  eminence,  the  microscope  is  more  than 
an  amusing  companion,  revealing  many  of  the  hidden  secrets  of  nature,  and  unveiling 
endless  beauties  which  were  heretofore  enveloped  in  the  impenetrable  obscurity  of 
their  own  minuteness. 

No  one  who  possesses  even  a  pocket-microscope  of  the  most  limited  powers  can 
fail  to  find  amusement  and  instruction  even  though  he  was  in  the  midst  of  the  Sahara 
itself.  There  is  this  great  advantage  in  the  microscope,  that  no  one  need  feel  in  want 
of  objects  as  long  as  he  possesses  his  instrument  and  a  sufficiency  of  light. 

Many  persons  who  are  gifted  with  a  thorough  appreciation  of  nature  in  all  her 
vivid  forms  are  debarred  by  the  peculiarity  of  their  position  from  following  out  the 
impulses  of  their  beings,  and  are  equally  unable  to  range  the  sea-shore  in  search  of 
marine  creatures  or  to  traverse  the  fields  and  woods  in  the  course  of  their  investigations 
into  the  manifold  forms  of  life  and  beauty  which  teem  in  every  nook  and  corner  of  the 
.country.  Some  are  confined  to  their  chambers  by  bodily  ailments,  some  are  forced  to 
reside  within  the  very  heart  of  some  great  city,  without  opportunities  of  breathing 
the  fresh  country  air  more  than  a  few  times  in  the  course  of  the  year ;  and  yet  there 
is  not  one  who  may  not  find  an  endless  series  of  Common  Objects  for  his  microscope 
within  the  limits  of  the  tiniest  city  chamber.  So  richly  does  nature  teem  with  beauty 
and  living  marvels,  that  even  within  the  closest  dungeton-walls  a  never  failing  treasury 
of  science  may  be  found  by  any  one  who  knows  how  and  where  to  seek  for  it. 

There  is  little  doubt  but  that  if  any  one  with  an  observant  mind  were  to  set  him- 
self to  work  determinedly  merely  at  the  study  of  the  commonest  weed  or  the  most 
familiar  insect,  he  would,  in  the  course  of  some  years'  patient  labor,  produce  a  work 
that  would  be  most  valuable  to  science  and  enrol  the  name  of  the  investigator  among 
the  most  honored  sons  of  knowledge.  There  is  not  a  mote  that  dances  in  the  sunbeam, 
not  a  particle  of  dust  that  we  tread  heedlessly  under  our  feet,  that  does  not  contain 
within  its  form  mines  of  knowledge  as  yet  unworked.  For  if  we  could  only  read 
them  rightly,  all  the  records  of  the  animated  past  are  written  in  the  rocks  and  dust  of 
the 'present. 

Microscopes  may  be  divided  into  two  classes,  simple  and  compound.  The  former 
class  may  contain  several  lenses  or  glasses,  but  generally  consists  of  a  single  lens ; 
but  the  Compound  Microscope  must  consist  of  at  least  two  glasses,  the  one  near  the 
object  to  be  examined,  and  commonly  called  the  objective,  the  other  near  the  eye,  and 
called  the  eye  piece.  This  class  is  subdivided  into  Monocular  and  Binocular  instru- 
ments, in  which  the  object  is  viewed  with  one  or  both  eyes,  as  their  names  imply. 
The  instruments  enumerated  in  the  following  Catalogue  are  arranged  under  these 
several  heads,  beginning  in  each  with  the  simple  and  inexpensive  forms,  and  leading 
up  to  the  most  perfect  yet  devised  by  skill  and  science.  We  have  of  each  kind  always 
in  stock  so  that  we  can  fill  orders  without  any  vexatious  delays,  and  our  customers 
may  depend  upon  having  all  mail  orders  attended  to  with  as  much  care  as  though 
they  made  a  personal  selection  for  themselves. 


34          JAMES    W.    QUEEN    &    CO.,    PHILADELPHIA    AND    NEW    YORK. 

A  few  hints  as  to  the  selection  of  a  Microscope  may  not  be  amiss  in  this  connection.. 
Those  who  fortunately  have  unlimited  means  at  their  command,  will  find  no  difficulty 
in  deciding  this  important  question,  since  it  was  long  ago  settled  that  the  highest 
grade  of  Binoculars  are  very  near  perfection,  and  leave  little  or  nothing  to  be  desired. 
But  to  the  far  larger  class  of  intending  purchasers,  the  question  of  cost  is  an  impor- 
tant one;  and  for  the  benefit  of  these  we  beg  to  oft'er  the  following  suggestions. 

A  common  mistake  with  novices  is  to  appreciate  the  excellence  of  a  microscope 
by  the  amount  of  its  magnifying  power.  Now,  in  truth,  no  object  should  be  viewed 
with  a  power  greater  than  sufficient  to  clearly  show  its  structure,  and  if  this  can  be 
done  with  twenty  diameters,  it  is  folly  to  apply  a  hundred.  And  this  is  especially 
the  case  with  low-priced  instruments,  where  the  actual  and  angular  apertures  of  the 
objectives  are  small,  and  the  corrections  not  so  exact  as  in  those  of  higher  grade,  ren- 
dering them  more  liable  to  give  false  impressions  of  the  object  under  examination. 
And  it  is  impossible  to  view  an  opaque  object  by  reflected  light,  satisfactorily,  with  any 
of  the  cheap  forms  of  Compound  Microscopes ;  the  lenses  approach  the  object  too  nearly, 
and  are  far  too  small  to  admit  of  a  proper  illumination  of  the  object.  For  a  child, 
just  learning  the  use  of  a  microscope,  and  who  will  naturally  desire  to  examine  the 
surface  of  any  object  he  may  pick  up.  or  for  those  of  riper  years,  who  may  possess  or 
contemplate  purchasing  a  compound  instrument,  but  who  will  be  obliged  to  dissect 
flowers,  insects,  &c.,  for  minute  examination,  a  Simple  Microscope  is  the  best  form, 
and  we  know  of  no  more  satisfactory  ones  than  1649  or  1650  of  this  Catalogue. 
These  are  simple  and  compact  in  form  and  construction,  easily  managed  by  even  the 
least  experienced,  give  clear  and  distinct  images  of  the  object  under  examination,  and 
are  cheap  enough  to  be  within  the  reach  of  all. 

After  becoming  familiar  with  the  use  of  the  simple  microscope,  and  of  the  objects 
suited  to  its  powers,  the  young  student  may  properly  supply  himself  with  a  Compound 
instrument  wherewith  to  penetrate  more  deeply  the  structures  of  which  he  has  until 
now  viewed  merely  the  surface  ;  and  in  order  to  meet  this  want  with  a  really  good  and 
reliable  instrument,  at  a  low  price,  we  some  years  ago  designed  and  brought  out  our 
Universal  Household  Microscope,  No.  1660,  which  we  believe  to  be  the  best  low-priced 
microscope  ever  made,  and  which,  by  reason  of  its  intrinsic  merits,  has  grown  so 
greatly  in  popular  favor,  that  it  is  almost  impossible  for  us  to  supply  the  great  and 
growing  demand  for  it.  It  is  so  fully  described  elsewhere  in  this  Catalogue,  that  a 
further  description  here  is  unnecessary ;  but  to  those  whose  means  will  not  allow  an 
outlay  of  at  least  Twenty  dollars  for  a  Microscope,  we  would  earnestly  say,  The 
Household  is  the  best  you  can  get  for  less  than  that  sum,  and  when  provided  with  an 
achromatic  object-glass,  No.  1660£  is  a  better  instrument  than  any  one  in  the  world 
possessed  fifty  years  ago. 

If  the  means  at  the  disposal  of  the  intending  purchaser  are  sufficient  to  enable  him 
to  procure  The  Educational  Microscope,  No.  1669,  we  would  single  it  out  from  among 
the  cheap  instruments  as  the  one  most  worthy  of  his  attention.  It  is  compact  and 
well  built,  of  a  graceful  form,  with  plenty  of  room  on  the  stage  for  any  kind  of  an 
object,  very  delicate  fine  adjustment  for  focus,  a  considerable  range  of  powers,  and  is 
admirably  adapted  to  the  examination  of  opaque  objects  as  well  as  transparent  ones. 
The  beautiful  phenomona  of  Polarized  Light  can  be  obtained  with  it  at  a  trifling  ad- 
ditional expense,  whilst  for  the  Young  Medical  Student,  its  compact  form,  moderate 
cost,  and  excellent  performance  on  all  classes  of  Anatomical  and  Pathological  prep- 
arations, are  cogent  recommendations. 

In  the  higher  grades  of  moderate-priced  instruments  our  Student's  Microscope  166& 
takes  a  front  rank.  The  illustration  gives  a  very  accurate  idea  of  the  general  appear- 
ance of  the  stand,  which  is  all  we  claim  it  to  be.  Beck's  Popular  Monoculars  and 
Binoculars,  B  222  and  B  220,  are  admirable  instruments  at  very  moderate  cost,  whilst 
for  those  who  are  not  obliged  to  count  this  very  closely,  the  larger  and  most  com- 
plete stands  of  Beck  or  our  own  Mr.  Zentmayer  leave  nothing  to  be  desired.  By  many, 
the  small,  inexpensive  stands  of  Hartnack  and  Nachett  are  preferred  to  all  others,  and 
they  are  certainly  very  compact  and  convenient.  In  the  choice  of  object-glasses  for 
the  better  stands,  we  shall  not  attempt,  to  guide  our  readers  in  this  place.  All  the 
leading  makers  have  their  votaries,  and  all  make  admirable  lenses.  We  have  them 
all  in  stock,  and  our  customers  have  the  advantage  of  comparison.  It  may  not  be 
amiss  to  remark  in  this  connection,  that  one  member  of  our  firm  has  had  a  long  ex- 
perience, and  some  little  reputation  as  a  microscopist,  and  that  no  objective  is  ever 
accepted  or  offered  for  sale  by  us,  which  has  not  been  inspected  and  approved  by 
him.  His  services  are  always  cheerfully  at  the  command  of  any  customer  in  the 
choice  of  an  object-glass  or  stand.

Having  thus  briefly  given  some  hints  as  to  the  selection  of  a  Microscope,  it  may 
not  be  amiss  to  add  a  few  on  the  preparation  of  objects  for  permanent  observation. 
We  cannot  of  course  in  the  limited  space  at  our  disposal  do  more  than  give  a  few  gen- 
eral directions;  for  further  details  the  student  is  referred  to  almost  any  of  the  elab- 
orate works  on  the  subject,  named  in  this  Catalogue  at  page  80.  The  indispensable 
requisites  are  neither  numerous  nor  costly.  Forceps,  1788  ;  Scissors,  1797  and  1809; 
Knives,  1801-1804;  Needles,  1805,  1806;  Turn-Table,  1814;  Brass  Table  and  Lamp, 
1815;  Glass  Slips,  1821;  Thin  Circles,  1839;  Ebonite  Cells,  1833;  Dropping  Tubes, 
1842;  Bell  Glass,  1845;  Canada  Balsam,  1847,  1848;  the  latter,  contained  in  Capped 
Bottles,  1863;  Glycerine,  1850;  Ditto  Jelly,  1851;  Preservative  Fluid,  1852;  Asphalt, 
1854;  Gold  Size,  1855;  White  Zinc  Cement,  1859;  Dropping  Bottles,  1869;  Labels, 
1950:  with  a  few  Camel  hair  pencils,  a  soft  linen  cloth,  chamois-skin,  and  three  or 
four  ounces  of  Liquor  Potassa,  will  constitute  a  very  respectable  outfit,  and  be  quite 
sufficient  for  mounting  all  the  ordinary  specimens  which  the  beginner  or  more 
advanced  student  may  desire  to  preserve. 

All  objects  must  be  mounted  in  one  of  three  ways :  dry  in  Air,  ditto  in  Balsam  or 
other  resinous  material,  or  moist  in  some  preservative  fluid  or  gelatinous  medium. 
For  the  first  method,  if  the  object  be  thin,  make  a  circle  with  the  Turn-table  and 
Zinc  cement  on  the  centre  of  a  glass  slip,  the  inner  diameter  of  which  shall  be  slightly 
smaller,  and  the  outer  diameter  as  much  larger,  than  the  covering  glass  you  wish 
to  use.  When  thoroughly  hard,  which  will  take  a  few  hours,  run  a  second  thin  coat- 
ing of  the  cement  on  top  of  the  first,  place  the  object  (previously  thoroughly  dried) 
in  the  centre  of  the  circle,  put  on  the  covering  glass  which  will  adhere  to  the  fresh 
cement,  and  finish  with  one  or  two  thin  coats  of  the  same.  If  the  object  be  thick, 
proceed  as  above,  using  Asphalt  instead  of  Zinc  cement,  and  an  Ebonite  ring  of 
proper  depth,  in  place  of  the  covering  glass  at  the  second  operation.  This  will  give 
you  a  convenient  cell  in  which  the  object  must  be  placed  and  secured  to  the  glass 
slip;  a  minute  portion  of  Gold  Size  is  the  best  cement  for  this  purpose  in  most  cases. 
The  whole  should  be  placed  under  a  bell  glass  until  thoroughly  dry,  when  a  fresh 
coating  of  Asphalt  must  be  applied  to  the  upper  surface  of  the  ring,  a  thin  cover 
applied  and  pressed  down,  finishing  with  successive  thin  coats  of  Asphalt.  Do  not 
use  paper  cells  in  dry  mountings;  they  always  admit  moisture,  and  the  object  is  soon 
spoiled.  Always  apply  your  cement  in  thin  layers.  Have  your  glass  slips  and  covers 
thoroughly  clean. 

For  mounting  in  Balsam,  the  specimen  must  be  entirely  free  from  moisture,  either 
by  drying  or  by  being  passed  through  Absolute  Alcohol  and  turpentine  ;  in  the  latter 
case  it  is  to  be  transferred  directly  from  the  turpentine  to  the  slide.  If  pure  Balsam 
1847  is  used,  a  drop  must  be  pressed  from  the  collapsible  tube  upon  the  centre  of  a  glass 
slide,  and  the  latter  placed  on  the  hot  table  1815  until  the  Balsam  spreads  out,  taking 
care  not  to  overheat  it.  The  object  must  now  be  placed  on  the  Balsam,  a  fresh  drop 
of  the  latter  pressed  on  top  of  it,  and  a  slightly  warm  cover  laid  upon  it,  in  such  a. 
manner  that  the  excess  of  Balsam  will  be  forced  out  beyond  the  opposite  edge  of  the 
cover  from  that  which  first  comes  in  contact  with  the  slide.  The  whole  must  then  be 
laid  in  a  warm  place  to  harden,  which  may  take  some  days  or  even  weeks.  Do  not 
be  annoyed  by  the  presence  of  air-bubbles,  they  will  all  disappear  before  the  Balsam 
becomes  hard.  If  the  prepared  Balsam  1848  is  used,  place  the  object  on  the  slide  and 
arrange  it  properly,  then  drop  a  small  quantity  of  the  Balsam  upon  it,  and  apply  the 
cover  as  before.  A  little  practice  will  enable  the  young  beginner  to  use  the  exact 
quantity  of  Balsam  necessary  to  make  a  neat  mounting.  If  any  excess  exudes  from  the 
edges  of  the  covering-glass,  it  may  be  cleaned  off  when  hard,  and  the  slide  finished  with 
a  layer  of  Prepared  Balsam  1848,  applied  with  a  Camel-Hair  pencil.  Never  use  colored 
cements  on  Balsam  mountings.  They  are  certain  to  run  in  and  spoil  the  slide. 

For  fluid  mountings,  almost  the  same  operations  as  in  dry  mountings  are  neces- 
sary. After  the  second  coating  of  cement  is  applied,  however,  the  cell  must  be  filled 
with  the  preservative  fluid,  the  object  (previously  soaked  in  the  same)  laid  in  it  and 
the  cover  applied  at  one  edge,  so  as  to  drive  out  the  excess  of  fluid  as  it  comes  down; 
this  excess  must  then  be  soaked  dry  with  blotting-paper  or  a  soft  towel,  and  a  thin 
coating  of  cement  at  once  applied,  to  be  followed  by  others  until  the  slide  is  quite  fin- 
ished. For  mounting  in  Glycerine  Jelly  the  same  rules  will  apply,  the  jelly  being 
first  liquefied  by  gentle  heat. 

Do  not  be  discouraged  by  failures  at  first;  a  little  practice  will  make  perfect.  Be 
cleanly  in  all  your  operations.  Dust  and  moisture  are  the  microscopist's  worst  foes. 
Persevere,  and  success  will  speedily  crown  your  efforts.

THE  CHILD'S  MIOKOSCOPE, 

No. 

1649.  The  Child's  Microscope, $3  50 

This  simple,  compact  and 
perfect  little  instrument 
.meets  a  want  long  felt, 
namely,  that  of  a  really 
good  and  efficient  Micro- 
scope, at  an  extremely  low 
price,  and  adapted  by  its 
simplicity  to  the  under- 
standing of  a  child.  The 
magnifiers  or  lenses  are 
three  in  number,  and  can 
be  used  separately  or  com- 
bined. With  the  lowest 
power,  or  largest  single 
lens,  a  large  insect,  such 
as  a  bee  or  fiy,  can  be 
examined  without  any  fur- 
ther preparation  than  plac- 
ing it  in  the  insect  box 
wh»«h  accompanies  the 
instrument.  With  the 
three  lenses  combined,  a 
power  of  700  times  can  be 
obtained,  which  is  quite 
sufficient  to  show  many  of 
the  larger  animalculae  in 
pond  ox  ditch  water,  the 
scales  from  a  butterfly's 
wing,  pollen  grains  of 
plants,  and  thousands  of 
other  interesting  and  easily 
obtained  objects  requiring 
considerable  magnifying 
power. 

The  illustration  gives  a  very  good  general  idea  of  the  instrument,  which  consists 
of  a  neat,  flat  mahogany  box,  as  a  base,  into  which  the  Microscope  packs  when  not 
in  use  ;  an  upright  brass  stem  which  screws  into  the  lid  of  the  box,  and  which  carries 
the  stage  on  a  sliding  tube  ;  and  at  its  top  firmly  fixed,  the  arm  which  holds  the  lenses. 
The  focus  is  adjusted  by  sliding  the  stage  up  or  down,  so  that  the  eye  is  not  obliged 
to  move  its  position  as  is  the  case  with  all  instruments  in  which  the  focussing  is 
effected  by  moving  the  lens.  The  mirror  for  reflecting  the  light  through  transparent 
objects  is  mounted  on  a  universal  joint,  so  as  to  be  readily  turned  in  any  direction 
toward  the  source  of  light.  A  brass  box  with  glass  bottom  and  top,  for  confining 
insects  whilst  under  examination,  and  a  small  pair  of  brass  forceps  for  placing  them 
within  it,  are  furnished  with  the  Microscope,  which  is  thus  a  compact  and  complete 
instrument  adapted  equally  to  the  comprehension  of  the  youngest  child,  and  to  the 
wants  of  the  more  advanced  scholar  or  botanist;  interesting  the  one  in  the  minute 
wonders  of  nature,  and  leading  its  infantile  mind  to  examine  into  the  mysteries  it 
unfolds,  and  aiding  the  other  in  his  various  studies  of  botany,  mineralogy  or  ento- 
mology. 

It  is  much  more  readily  managed  by  a  novice  than  a  Compound  Microscope,  and 
has,  with  the  three  lenses  combined,  almost  as  much  magnifying  power  as  the  cheap- 
est of  the  latter ;  whilst  unlike  it,  "  The  Child's  Microscope"  is  equally  well  adapted 
to  the  examination  of  large  opaque  objects,  such  as  beetles,  flies  or  flowers.  It  can- 
not be  put  out  of  order,  excepting  by  considerable  violence  sufficient  to  break  it,  and 
any  ordinary  child  can  be  trusted  with  its  use. 

Rev.  Mr.  Wood's  excellent  little  work,  "  The  Common  Objects  of  the  Microscope," 
No.  1980  of  this  Catalogue,  is  an  excellent  companion  to  the  "  Child's  Microscope," 
giving  full  direction  as  to  its  use,  and  the  collection  and  preparation  of  objects  for 
examination.

1650.  The  School  Microscope,          .  $6  00 

This  instrument  consists  of  a  tubular  stem  about  five  inches  high,  the  lower  end  of 
which  screws  firmly  into  the  lid  of  the  box  wherein  the  instrument  is  packed  when 
not  in  use.  To  the  upper  end  of  this  stem  the  stage  is  firmly  fixed  ;  while  the  lower 
end  carries  a  concave  mirror.  Within  the  tubular  stem  is  a  round  pillar  having  a 
rack  cut  into  it,  against  which  a  pinion  works  that  is  turned  by  a  milled  head :  and 
the  upper  part  of  this  pillar  carries  a  horizontal  arm  which  bears  the  lenses,  so  that 
by  turning  the  milled  head,  the  arm  may  be  raised  or  lowered,  and  the  requisite  focal 
adjustment  obtained.  Three  magnifiers  are  supplied,  and  by  using  them  either  sep- 
arately or  in  combination,  a  considerable  range  of  powers  from  about  five  to  forty 
diameters  is  obtained.  A  condensing  lens  for  opaque  objects,  a  pair  of  brass  forceps, 
and  pliers,  and  an  aquatic  box  for  the  examination  of  objects  in  water,  are  also  sup- 
plied. This  instrument  is  peculiarly  adapted  for  educational  purposes,  being  fitted 
in  every  particular  for  the  examination  of  botanical  specimens,  small  insects  or  parts 
of  insects,  water-fleas,  the  larger  animalcules,  and  other  such  objects  as  young 
people  may  readily  collect  and  examine  for  themselves :  and  those  who  have  trained 
themselves  in  the  application  of  it  to  the  study  of  nature  are  well  prepared  for  the 
advantageous  use  of  the  Compound  Microscope.  But  it  also  affords  to  the  scientific 
inquirer  all  that  is  essential  to  the  pursuit  of  such  investigations  as  are  best  followed 
out  by  the  concurrent  employment  of  a  Simple  and  a  Compound  Microscope,  the  for- 
mer being  most  fitted  for  the  preparation,  and  the  latter  for  the  examination  of  many 
kinds  of  objects  ;  and  it  may  be  easily  adapted  to  the  purposes  of  dissection  by  placing 
it  between  arm  rests  or  blocks  of  wood,  or  books  piled  one  on  another  so  as  to  give 
a  support  for  the  hand  on  either  side,  at  or  near  the  level  of  the  stage.

1651-52.    (Open.) 

The  construction  and  method  of  using  this  Microscope  is  very  simple,  and  will  be 
readily  understood  from  an  inspection  of  the  engravings.  It  consists  primarily  of  a 
small  wooden  case,  the  exact  size  of  that  shown  in  the  engravings.  To  one  end  of  the 
lid  of  this  case  is  attached  one  of  the  ends  of  the  box  ;  and  when  the  lid  is  reversed  and 
turned  upside  down,  it  may  be  slid  into  the  groove  of  the  case,  and  then  forms  a  stand 
for  the  lenses  and  glass  stage,  as  shown  in  Fig.  1651-52.  (Open.)  The  lenses  and  stage 
are  supported  by  a  steel  rod,  the  lower  end  of  which  is  hinged  to  the  lid,  so  that  it  may , 
be  turned  down  and  lie  in  a  groove  provided  for  it.  When  raised  into  the  position 
shown  in  the  figure,  it  is  held  very  securely  in  place  by  means  of 'a  button ;  and  this 
button  also  serves  to  retain  it  in  the  groove  when  it  is  turned  down.  The  glass  stage,, 
which  is  fitted  into  a  frame  of  hard  rubber,  slides  easily  on  the  stem,  so  as  to  be 
readily  adjustable  for  focus,  while  at  the  same  time  it  may  be  firmly  fixed,  by  means 
of  a  set-screw,  at  any  desired  height,  and  will  then  serve  as  a  stage  for  dissecting 
purposes.  The  frame  which  holds  the  lenses  fits  on  to  the  top  of  the  stem.  A  mirror 
is  fitted  into  the  case,  and  is  readily  adjustable  by  means  of  the  button  shown  on  the 
outside,  so  that  light  may  be  reflected  up  through  the  stage  when  the  objects  to  be 
examined  are  transparent ;  and  when  they  are  to  be  viewed  by  reflected  light,  there 
is  a  dark  ground  of  hard  rubber,  which  is  nlso  carried  by  the  stem,  and  may  be 
turned  under  the  stage,  so  as  to  cut  off  all  transmitted  light.  Dissecting  needles, 
with  neat  handles,  fit  into  appropriate  grooves.

1651-52.     (Closed.) 

As  a  dissecting  microscope  for  botanical,  entomological,  and  physiological  work, 
this  instrument  is  very  efficient  and  convenient.  The  glass  plate  is  fitted  into  the 
stage  so  as  to  form  a  cell  capable  of  holding  water,  so  that  dissections  may  be  carried 
on  under  that  liquid,  or  aquatic  animals  may  be  kept  alive  and  examined  at  leisure. 
The  stage  may  also  be  turned,  so  that  the  flat  side  will  be  up  when  so  desired.  When 
the  lenses  and  stage  are  removed,  they  are  readily  packed  in  the  case,  as  shown  in  Fig. 
1651-52  (Closed) ;  the  stem  is  then  turned  down  and  held  in  its  groove  by  the  button; 
the  lid  is  drawn  out  of  the  groove,  turned  over,  and  replaced  so  that  the  vertical  piece, 
to  which  the  button  is  attached,  closes  the  open  end  of  the  box,  and  the  whole  thing 
is  packed,  into  a  compass  which  readily  admits  of  its  being  carried  in  the  vest  pocket. 

After  reading  this  description,  probably  the  first  question  that  will  rise  to  the  lips 
of  the  reader  is  —  What  will  such  a  microscope  do? 

The  lenses  being  well  made,  and  provided  with  a  proper  diaphragm,  which  secures 
distinctness  of  definition,  may  be  used  either  singly  or  together.  Some  of  the  instru- 
ments are  provided  with  three  lenses,  and  some  with  but  two.  These  lenses  give  a 
range  of  power  of  from  five  to  thirty  diameters,  (twenty-five  to  nine  hundred  times 
the  surface,)  the  first  being  admirably  adapted  to  the  examination  of  minerals,  textile 
fibres  and  fabrics,  the  larger  parts  of  flowers  and  insects,  etc.,  while  the  latter  is 
sufficiently  powerful  to  enable  the  student  to  dissect  flowers,  and  examine  their  more 
minute  structure  with  great  efficiency.  Under  good  management,  it  will  show  the 
individual  corpuscles  in  the  blood  of  the  frog. 

Its  applications  are  as  follows:  In  the  arts  it  may  be  applied  to  the  examination  of 
materials,  to  the  measurement  of  minute  spaces,  and  to  an  examination  of  the  quality 
of  the  finer  kinds  of  work.  It  is  the  more  readily  applicable  to  these  purposes  from 
the  fact  that  the  frame  holding  the  lenses  may  be  separated  from  the  rest  of  the 
microscope,  and  used  by  itself.  By  the  addition  of  a  thin  piece  of  hard  rubber,  which 
slides  on  the  stem  and  is  pierced  with  an  opening  of  proper  size,  this  microscope  may- 
be used  as  a  most  efficient  linen  prover.  As  a  microscope  for  detecting  counterfeit 
money,  it  cannot  be  surpassed. 

On  the  farm  it  will  enable  the  agriculturist  to  examine  the  various  noxious  insects 
and  forms  of  fungi  and  blight,  and  thus  aid  him  in  identifying  them  and  applying  the 
proper  remedy.  In  the  examination  of  minute  seeds,  such  as  timothy,  clover,  etc.,  it 
will  also  prove  a  very  valuable  assistant  to  the  farmer,  enabling  him  to  detect  any 
inferiority  in  the  quality  or  any  impurity  or  adulteration.  Frequently  the  seeds 
offered  in  market  contain  minute  seeds  of  offensive  weeds,  many  of  which  are  so  small 
that  they  are  not  easily  discovered  by  the  naked  eye.

THE  COLLEGE  MICROSCOPE. 


1653. 

No.  PRICK. 

1653.  College  Microscope,  complete  with  all  the  apparatus  described  below, 

in  fine  mahogany  case,    .........     $40  00 

The  College  Microscope  has  been  designed  for  the  use  of  students,  likewise  as  a 
seaside,  travelling,  or  working  microscope.  It  is  both  compound  and  simple,  and  has 
a  joint  for  inclining  the  instrument,  and  rack  adjustment  for  focusing.  It  is  fitted 
in  a  polished  mahogany  case,  six  inches  cube,  and  so  arranged  that  on  opening  the 
case  the  instrument  stands  on  the  table  ready  for  use,  and  the  appliances,  though 
numerous,  exposed  to  view  and  readily  accessible. 

The  objectives  of  the  compound  microscope  arc  achromatic,  and  useable  separate 
or  combined,  giving  powers  of  200,  100,  and  50  diameters.  The  body  elongates  to 
give  extra  power.  For  use  as  a  simple  microscope  three  simple  objectives  are  sent, 
useable  separately  or  combined,  giving  powers  with  No.  1,  5  ;  No.  2,  7  ;  No.  3,  11 ;  No. 
1,  2,  and  13;  No.  1  and  3,  16;  No.  1,  2,  and  3,  20  diameters. 

The  case  contains  a  complete  set  of  apparatus  and  materials  required  in  mounting 
objects,  including  turn-table,  hot-plate  with  spirit  lamp,  dissecting  trough,  a  complete 
set  of  materials  and  implements  ordinarily  required,  with  a  stock  of  glass  sides,  cover 
glasses,  cells,  and  labels.  The  portability  and  compactness  of  this  apparatus  allows 
of  its  being  conveniently  taken  into  the  country  or  sea-side  for  use  on  the  spot,  thus 
affording  the  valuable  advantage  of  not  only  being  able  to  examine  but  also  readily 
to  mount,  whilst  in  fresh  and  perfect  condition,  objects  that  are  liable  to  become  use- 
less or  seriously  injured  in  microscopic  value  if  the  mounting  has  to  be  deferred  until 
returning  home. 

The  Dissecting  Trough  is  placed  in  the  recess  of  the  stage  in  place  of  the  stage  plate, 
for  the  purpose  of  examining  or  dissecting  an  object  under  water,  pinned  down  upon 
the  loaded  cork  or  not,  as  required. 

The  Turn-table  is  carried  upon  a  long  spindle  passed  through  a  hole  in  the  stage, 
giving  a  very  steady  and  free  motion,  and  the  right  hand  is  steadily  supported  by  the 
microscope  arm  close  over  the  turn-table  whilst  making  varnish  rings.  The  top  of 
the  turn-table  is  made  only  the  size  of  a  glass  slide  and  the  slide  is  held  in  ita 
place  by  slipping  it  under  an  india  rubber  band,  which  holds  it  so  firmly  as  to  prevent 
any  risk  of  shifting. 

The  Hot-plate  is  placed  in  the  recess  of  the  stage,  the  microscope  arm  being  then 
reversed  in  position  to  be  clear  of  the  stage,  and  the  stand  placed  in  the  opposite 
position  to  the  one  in  wrhich  it  is  used  as  a  microscope,  the  spirit  lamp  being  placed 
in  the  position  of  the  mirror.  The  heated  slide,  with  ring  of  marine  glue  upon  it,  is 
readily  and  quickly  shifted  from  the  hot-plate  into  the  rceess  in  the  bottom  board, 
and  centred  there  at  once  by  pushing  it  home  in  the  recess,  for  centering  the  cell  whilst 
Btill  hot  enough  to  keep  the  marine  glue  melted.

In  Preparing  Crystals  of  salts  as  polarizing  objects,  the  microscope  arm  is  used  as 
•a  retort  stand  for  holding  the  watch  glass  for  evaporating  over  the  spirit  lamp :  the 
stage  plate  being  left  in  its  place  for  warming  the  slide  and  coverglass  at  same  time. 
The  microscope  arm  serves  also  as  a  stand  for  filtering  the  liquids  used  in  mounting 
by  placing  a  small  folded  funnel  of  blotting  paper  in  the  ring  of  the  arm,  and  setting 
the  bottle  to  be  filled  below  the  stage. 

The  following  Materials  for  Mounting  are  contained  in  the  set  of  bottles.  The  rack 
containing  them  can  be  taken  out  of  the  case  when  in  use,  or  any  single  bottle  is  ac- 
cessible whilst  remaining  in  the  case. 

Asphalte  Varnish,  for  finishing  off  slides,  and  making  varnish  cells. 

Gold  Size,  for  fixing  cover-glasses,  &c. 

Liquid  Marine  Glue,  for  making  cells  and  cementing  cells  on  slides. 

[These  are  in  bottles  having  a  small  camel  hair  brush  fixed  through  the  cork,  and 
always  immersed  in  the  liquid  and  ready  for  use  without  risk  of  the  fingers  getting 
touched  with  the  varnish.  The  asphalte  and  goldsize  are  kept  diluted  by  occasional 
addition  of  benzole,  so  as  to  drop  freely  from  the  brush.] 

Turpentine,  for  cleaning  off  waste,  slides,  &c.,  in  similar  bottle,  with  brush  fixed  in 
the  cork. 

[These  four  bottles  are  fitted  tightly  into  the  rack,  so  that  the  brush  and  cork  is 
readily  taken  out  by  one  hand  whilst  the  other  hand  is  occupied.] 

Canada  Balsam  diluted  with  benzole  sufficiently  for  dropping  freely  from  the 
lipped  bottle  ;  the  cork  is  readily  removed  after  being  carefully  loosened,  and  the  di- 
luted balsam  is  used  cold,  the  cover-glass  of  an  object  being  kept  down  by  a  spring 
clip ;  the  slide  being  then  left  in  a  slightly  warm  situation,  as  upon  a  chimney  piece, 
all  the  air  bubbles  become  removed  in  a  few  hours  beyond  the  edge  of  the  cover-glass, 
in  the  course  of  the  evaporation  of  the  benzole,  and  the  superfluous  balsam  can  be 
scraped  off  after  a  few  days. 

Alcohol,  in  lipped  bottle,  for  cleaning  off  cells  fixed  by  marine  glue,  and  cleaning 
objects  for  mounting,  &c.  In  cleaning  off  marine  glue,  after  removing  it  with  the 
scraper  to  nearly  the  edge  of  the  cell,  working  under  the  microscope  with  light  from 
below,  the  cleaning  is  carefully  finished  at  the  edge  with  alcohol  and  the  scraper. 

Chloroform,  for  cleaning  cover-glasses  and  slides,  diluting  varnish,  &c.,  and  for 
killing  and  cleaning  insects,  &c. 

Liquor  Potassse,  for  softening  and  bleaching  the  hard  coverings  and  antennae,  &c.  of 
insects. 

Goadby's  Fluid,  for  mounting  animal  objects. 

Glycerin  and  Carbolic  Acid  Water,  for  mounting  vegetable  objects  consisting  of 
glycerin  mixed  with  thirty  times  the  quantity  of  distilled  water  in  which  carbolic 
acid  has  been  soaked,  the  whole  being  filtered. 

Distilled  Water,  in  larger  bottle,  for  washing  objects  for  mounting  The  contents 
of  these  bottles  are  filtered  with  advantage  after  remaining  in  use  for  some  time,  to 
remove  particles  of  dust,  &c. 

Needles,  Forceps,  large  and  small,  dissecting  knife,  scraper,  stage  forceps,  and  spring 
clips,  are  contained  in  one  drawer. 

Dipping  Tubes  and  Brushes  in  the  opposite  drawer ;  kept  separate  to  prevent  any 
risk  of  rusting  the  needles,  &c. 

Cover -glasses,  Cells,  and  Labels  in  the  smaller  drawer ;  and  two  dozen  glass  slides  in 
the  bottom  of  case,  with  watch  glasses  and  a  small  wiper  for  finishing  the  cleaning 
of  cover-glasses  and  slides,  to  be  kept  quite  clean  and  free  from  dust  and  grease. 

The  double  ring  handle  at  top  of  case  prevents  any  risk  of  the  case  opening  when 
carried  by  the  handle  if  not  locked.

No.  PRICK. 

1660.  The  Universal  Household  Microscope, $6  00 

This  is  the  most  convenient,  complete  and  powerful  Microscope  ever  offered  for  the 
low  price  of  $6  00.  It  has  the  important  parts  of  a  first-class  instrument,  is  readily 
adjusted,  and  well  calculated  not  only  to  amuse  but  instruct  young  persons,  and 
thereby  foster  a  taste  for  the  study  of  Natural  History.  It  has  a  firm  tripod  base  of 
cast  iron,  and  the  facility  for  inclining  to  any  angle  for  convenience  of  observation ; 
a  concave  mirror  for  concentrating  the  rays  of  light  upon  the  object ;  an  adjustable 
eye-piece  or  draw-tube,  and  two  object-glasses  of  different  powers;  all  packed  in  a 
neat  wooden  box  with  hinges  and  hooks.  No  microscope  of  equal  power  and  neatness 
of  finish  has  ever  been  offered  for  the  same  low  price  ;  and  no  more  instructive  or 
entertaining  gift  can  be  made  to  young  persons.  It  has  a  magnifying  power  of  from 
20  to  100  diameters,  or  400  to  105000  times  the  area. 

MAGNIFYING  POWERS. 

Objective  No.  1  is  the  lowest  power,  and,  with  the  tube  closed,  gives  a  power  of  20 
diameters  or  400  times  the  area  ;  with  the  extension  tube  drawn  out  to  three  inches, 
the  power  is  40  diameters  or  1600  times  the  area. 

Objective  No.  2,  with  the  tube  closed,  gJves  a  power  of  50  diameters  or  2500  times 
the  area ;  with  the  extension  tube  drawn  out  to  three  inches,  the  power  is  100  dia- 
meters or  10,000  times  the  area. 

The  magnifying  power ,  as  understood  by  microscopists,  is  in  diameters.  A  popular  way 
is  to  give  the  area  or  super/ices  ;  and,  as  th*  object  is  magnified  equally  in  all  directions,  this 
power  is  obtained  by  squaring  the  diameter. 

We  have  a  great  variety  of  objects,  neatly  prepared  and  mounted  on  glass  papered 
slides,  with  name  on  each,  well  calculated  for  the  Household  Microscope.  We  sell 
them  at  the  low  prices  of  $2  00  per  dozen,  or  20  cents  for  any  single  slide. 

A  suitable  and  interesting  Book  on  the  Microscope,  with  directions  for  collecting 
and  preparing  the  objects,  can  be  had  with  it.     Price  50  cents,  with  400  colored 
illustrations.

QUEEN'S  POPULAR  MICROSCOPE, 


1664  J.  Queen's  Popular  Microscope.  This  Stand,  as  its  name  imports,  has 
been  designed  and  constructed  by  us  expressly  for  popular  use,  and 
places  within  the  reach  of  all  a  full-sized  instrument  of  first-class 
workmanship,  capable  of  carrying  objectives  of  any  make,  and  all 
the  accessories  of  Queen's  Student's  Microscope,  so  that  in  addition 
to  the  ordinary  objects  usually  viewed  in  the  microscope,  all  the 
beautiful  phenomena  of  Polarized  Light,  Dark  Field  Illumination, 
&c.,  &c.,  are  exhibited  by  it  in  the  most  satisfactory  manner. 

The  Stand  is  14  inches  high,  the  base  being  of  iron,  handsomely 
japanned  in  a  light  bronze  color,  and  very  firm  and  steady.  Body, 
stage,  and  movements  all  of  highly  finished  brass.  The  coarse 
adjustment  of  focus  is  made  by  a  friction  pinion  and  milled  heads, 

,  the    fine    adjustment   by  a   lever  working    so    delicately  that   the 

highest  powers  may  be  used  with  the  greatest  accuracy.  There  is 
sufficient  length  of  motion  in  the  body  to  admit  of  using  a  2-inch 
objective.  The  stage  is  very  large  and  roomy,  with  a  thin  super- 
stage  or  object-carrier,  having  a  very  delicate  movement  in  every 
direction  of  more  than  one  inch.  The  Mirror  is«  mounted  in  the 
most  approved  manner,  admitting  the  greatest  obliquity  of  illumi- 
nation, and  the  body  is  fitted  with  the  Society  Screw,  allowing 
objectives  of  any  make  to  be  used.  Beneath  the  stage  is  a  revolving 
diaphragm  of  various  sized  openings,  carried  in  a  tube,  which  also 
holds  the  Polarizing  Prism  or  other  accessories  when  in  use. 

The  price  of  this  really  excellent  microscope  has  been  fixed 
very  low,  which  must  insure  a  large  sale.  With  One  Eye-Piece, 
and  No.  8  French  Object  Glass,  giving  powers  from  about  60  to 
300  diameters;  Condensing  Lens  on  separate  stand  for  opaque 
objects;  Needles  and  Forceps;  and  packed  in  a  neat  oiled  walnut 
case,  with  good  brass  handle  and  lock,  the  cost  is  only

No.  PRICE. 

1669.  THE  EDUCATIONAL  MICROSCOPE, .         .    $37  60 

This  is  believed  to  be  the  best  low  priced  Microscope  ever  offered  to  the  public,  and 
it  may  safely  be  relied  upon  as  capable  of  performing  all  the  work  required  by  the 
young  student  in  any  department  of  Microscopical  science.  It  is  not  of  course  ex- 
pected that  it  will  bear  comparison  with  Microscopes  of  many  times  its  cost,  but  it  is 
infinitely  superior  to  the  best  Microscope  ever  constructed  on  the  old  (non-achroma- 
tic) plan.  The  simplicity  of  its  construction,  and  the  facility  with  which  all  those 
adjustments  may  be  made  that  are  required  for  the  purposes  it  is  intended  to  fulfill, 
constitute  with  its  low  price,  a  great  recommendation  to  those  who  value  a  Microscope 
rather  as  a  means  of  interesting  recreation  for  themselves,  or  of  cultivating  a  taste  for 
the  study  of  nature,  and  a  habit  of  correct  observation  in  the  young,  than  as  an  in- 
strument of  scientific  research. 

The  stand  is  entirely  of  brass,  of  handsome  proportions,  and  well  finished ;  th«? 
compound  body  is  mounted  upon  a  double  axis  joint,  allowing  the  instrument  to  be 
inclined  at  any  angle  convenient  to  the  observer,  with  quick  rack  adjustment  and  fine 
screw  adjustment  for  focus,  sliding  object-holder,  plane  and  concave  mirrors,  wheel 
of  diaphragms,  and  the  following  accessories : 

2  Eye  Pieces.

CKOUCH'S  BINOCULAB  MICKOSCOPE, 


1710. 

This  is  one  of  the  best  instruments  of  its  class  in  use,  and  we  strongly  recommend 
it  to  such  as  desire  to  possess  a  Binocular  at  once  cheap,  good,  and  portable.  Its 
general  arrangement  is  shown  in  the  illustration  above,  the  double  body  being  sup- 
ported on  a  "limb"  on  the  Lister  model.  The  adjustment  of  the  eye-pieces  for  the 
distance  of  the  eyes  is  made  by  a  transverse  bar  which  is  attached  to  one  of  them, 
and  which  works  through  a  slot-piece  fixed  to  the  other;  so  that  if,  by  the  applica- 
tion of  the  finger  and  thumb  to  the  projecting  pin,  the  bar  with  the  attached  eye- 
piece be  raised  or  lowered,  the  other  eye-piece  also  is  moved  accordingly.  The 
stage  is  circular  in  form,  and  consists  of  a  plate  of  polished  black  glass,  over  which 
the  object-holder  slides  in  every  direction  with  the  greatest  facility,  and  is  so  ar- 
ranged as  to  afford  entire  concentric  rotation  in  the  optic  axis ;  an  indispensable 
feature  in  a  good  Binocular  instrument. 


JAMES    W.    QUEEN    A    CO.,    PHILADELPHIA    AND    NEW    YORK.          55 

This  Microscope  in  its  "Binocular"  form,  the  first  introduced  to  the  scientific 
public  at  a  reasonable  cost,  has  steadily  increased  in  reputation,  and  has  now 
attained  the  highest  position  of  any  microscope  of  its  class.  Its  thorough  excel- 
lence of  performance,  stability  in  any  position  (in  this  respect  being  unrivalled), 
simplicity  of  construction,  and  consequent  non-liability  to  derangement,  render  it 
by  far  the  most  perfect  working  microscope  extant.  It  has  now  for  many  years 
been  favored  with  the  approval  of  Dr.  Carpenter,  as  his  own  working  microscope, 
and  was  the  instrument  selected  for  use  by  him  on  the  important  expedition  of 
H.  M.  S.  "Porcupine."

A  full  list  of  these  will  be  found  in  Beck's  special  catalogue  at  the  end  of  this. 

Objectives  by  Crouch,  Nachett,  Tolles,  Wales,  and  Zentmayer,  always  in  stock.  Price 
lists  will  be  sent  on  application.  These  are  all  furnished  with  the  "Society  Screw," 
unless  specially  ordered  otherwise. 

We  would  call  special  attention  to  the  French  Objectives,  a  list  of  which  will  be  found 
on  the  following  page.  These  are  not  the  ordinary  commercial  lenses  usually  sold 
at  low  prices,  and  most  of  which  are  mere  toys,  but  are  good,  well-corrected  glasses, 
made  especially  for  us  by  one  of  the  most  eminent  Opticians  of  Paris,  and  we  guar- 
antee their  performance  to  be  satisfactory.  If  cheaper  lenses  are  wanted,  we  have 
those  usually  sold,  in  stock,  at  prices  about  25  per  cent,  less  than  the  following  list.

1867.  Fiddian's  Microscope  Illuminator,  nickel  plated, 

This  very  convenient  and  useful  Lamp  has  been  designed  to  combine  the  qualities 
of  other  Microscope  Lamps,  together  with  greater  portability,  the  whole  fitting  into 
a  brass  tubular  box,  the  exterior  of  which  is  covered  with  morocco  leather,  the  lid 
forming  the  stand  of  the  Lamp.  The  metallic  chimney  being  telescopic,  occupies  a 
very  small  compass ;  the  condenser  fits  into  the  cell  in  front.  The  reservoir  is  of 
brass,  and  will  contain  sufficient  petroleum  for  six  hours'  consumption.  The  entire 
Lamp  fitting  into  the  case  from  the  top,  escape  of  the  oil  is  prevented. 

In  trimming  the  Lamp  care  should  be  taken  that  the  wick  is  perfectly  dry,  and 
the  petroleum  of  good  quality:  also  that  none  of  the  oil  gets  upon  the  metallic  chim- 
ney or  reservoir,  or  a  bad  smell  will  be  given  off  until  the  oil  is  burnt  away. 

In  using  the  Lamp  it  will  be  found  convenient  to  slightly  incline  it,  so  as  to  bring 
the  broad  surface  of  the  flame  more  parallel  with  the  surface  of  the  mirror  of  the 
microscope. 

When  it  is  necessary  to  re-line  the  chimney,  screw  off  the  sliding  portion,  wash 
out  the  old  lining,  and  re-coat  it  with  superfine  Plaster  of  Paris.     When  dry  it  will 
be  found  ready  for  use  —  a  few  minutes  will  be  found  sufficient  to  do  this.

Microscopists  will  find  this  new  form  of  COLLECTING  BOTTLE  an  indispensable  com- 
panion in  their  Pond-hunting  Excursions,  for  collecting  and  retaining  the  various 
minute  objects  that  may  be  obtained  in  water  by  the  dipping  bottle.     It  consists  of  a 
bottle  with  a  movable  brass  cap,  in  which  is  fastened  two  small  tubes  with  screw 
tops.     One  of  these  (A)  projects  a  little  higher  than  the  other  ;  in  which  is  fixed  the 
funnel  (C)  when  in  use.     The  other  tube  (B)  has  a  trumpet-shaped  form,  across  the 
mouth  of  which  a  piece  of  fine  muslin  is  stretched;  the  loose  funnel  shown  is  placed 
in  the  outer  tube,  and  the  water  containing  the  various  organisms  which  it  is  wished 


JAMES    W.    QUEEN    &    CO.,    PHILADELPHIA    AND    NEW    YORK. 


to  retain  is  poured  into  it.  As  soon  as  the  bottle  is  full  the  water  rises  through  the 
porous  material  placed  across  the  lower  end  of  this  inner  tube,  and  flows  over  re- 
taining behind  and  in  the  bottle  the  various  diatoms,  volvox,  desmids,  entomostraca,  <^c., 
which  may  have  been  floating  therein.  Any  quantity  of  water  may  be  deprived  of 
the  minute  objects  floating  in  it,  without  the  troublesome,  imperfect  and  destructive 
process  of  first  filtering  through  a  piece  of  muslin  or  flannel,  and  then  reversing  the 
filtering  material  in  the  mouth  of  the  bottle,  to  detach  the  deposit. 
For  collecting  larger  objects,  the  cap  of  the  bottle  can  be  removed.

HOLMAN'S  LIFE  AND  CURRENT  SLIDES. 

These  very  useful  and  ingenious  accessories  to  the  Microscope  are  attracting  great 
attention  among  scientific  men  everywhere,  and  have  received  the  strongest  commen- 
dations from  Medical  and  other  Scientific  Journals  at  home  and  abroad.  By  an 
arrangement  with  the  inventor  we  are  enabled  to  supply  them  to  our  customers  of  the 
most  perfect  quality,  each  one  having  passed  through  Mr.  Holman's  hands  before 
being  delivered,  to  us.

HOLMAN'S  LIFE  SLIDE,  with  Cover,  in  a  neat  Box,  .  .  .  .  $1  50 
THE  LIFE  SLIDE  consists  of  a  plate  of  thick  glass  3x1  inch,  with  a  deep  oval  cavity 
ground  in  its  centre,  to  contain  the  mass  of  material  under  observation.  Around  the 
margin  of  this  oval  cavity  is  a  polished  bevel,  and  from  the  bevel  extends  a  small  cut, 
the  object  of  which  is  to  afford  an  abundance  of  fresh  air  to  the  living  things  within. 
It  is  found  upon  enclosing  the  animalculae,  etc.,  that  they  will  invariably  seek  the 
edge  of  the  pool  in  which  they  are  confined,  and  the  bevelled  edge  permits  the  observer 
to  take  advantage  of  this  disposition ;  for  when  beneath  it,  the  objects  are  within  the 
range  of  the  highest  powers. 

The  Life  Slide  is  constructed  to  retain  the  greatest  quantity  of  material  under  the 
smallest  cover  glass,  and  is  designed  to  be  used  with  the  highest  powers  of  the  Mi- 
croscope for  studying  the  Bacteria,  Vibriones,  and  other  low  forms  of  life.  For 
studying  the  circulation  of  the  blood  in  the  tail  of  the  Tadpole,  it  is  the  most  perfect 
contrivance  imaginable.  The  deep  oval  cavity  will  contain  the  body  of  a  small  Tad- 
pole, whilst  the  tail  lies  extended  in  the  bevelled  portion,  and  may  be  examined  with 
the  highest  powers.  Another  very  important  feature  in  the  device  is  the  fact  that  a, 
preparation  may  be  kept  with  it  for  days  or  weeks  together  without  losing  vitality, 
owing  to  the  simple  arrangement  for  supplying  fresh,  air.

The  Current  Slide  consists  of  slip  of  plate  glass  3x1  inch,  in  which  two  oval  concave 
cells  are  ground,  there  being  a  space  of  ^  in.  left  between  the  cells.  These  cells, 
which  are  about  £  in.-  in  diameter  and  as  deep  as  the  glass  will  permit  —  say  -fa  in. 
deep  —  are  united  by  a  very  shallow  channel  somewhat  below  the  centre  of  the  two 
cells,  so  that  with  cells  placed  -fa  in.  apart,  the  channel  is  about  -fa  in.  long.  Both 
the  cells  and  channel  are  polished.  If  a  few  drops  of  blood  be  placed  in  these  cells, 
and  a  cover  of  thin  glass  be  pressed  down,  some  of  the  blood,  finding  its  way  between 
the  surfaces  in  contact,  will  dry,  and  act  as  a  cement  to  hold  the  fluid  blood  in  the 
cells  in  place.  The  quantity  of  blood  being  insufficient  to  fill  the  cells,  a  considerable 
amount  of  air  becomes  imprisoned  with  the  blood,  and  the  expansion  of  the  air  in 
either  cell  will  drive  the  blood  through  the  channel  into  the  adjacent  cell,  and  in  the 
shallow  channel  it  is  presented  under  the  most  favorable  condition  for  examination. 
By  holding  the  top  of  the  finger  near  one  or  the  other  cell,  the  heat  is  enough  to  cause 


JAMES    W.    QUEEN    &    CO.,    PHILADELPHIA    AND    NEW    YORK.  6T 

the  expansion  and  a  consequent  more  or  less  rapid  flow  of  the  fluid  through  the  chan- 
nel. This  flow  may  be  arrested,  or  continued  and  reversed  at  will,  by  change  of 
position  of  the  finger,  so  that  any  particles  floating  in  the  liquid  can  pass  in  succession 
across  the  field,  but  can  be  arrested  and  examined  with  ease  at  will. 

So  sensitive  is  the  apparatus,  that  even  with  the  highest  powers,  a  corpuscle, 
granule,  or  cell  in  the  field  of  view,  may  be  leisurely  turned  over  and  over  in  any 
desired  position,  thus  affording  an  unequalled  means  of  observation  and  study  to  the 
microscopist ;  and  while  the  eye  is  examining  at  leisure  the  behavior  of  the  objects 
beneath  it,  the  mind  is  charmed  with  the  simplicity  of  the  means  by  which  their 
motions  are  controlled. 

Blood  or  other  fluid  inclosed  in  the  cetls  remains  in  good  condition  for  examination 
for  several  days,  and  changes  undergoing  in  the  fluid  can  be  examined.

Cover,  but  without  Bottles,      .  .  .  .  .  .      $4  50 

This  is  a  modification  of  the  "LIFE"  and  "CURRENT"  slides,  whereby  living  objects 
of  suitable  size  and  habits  can  be  retained  under  observation  uninterruptedly  for 
days  or  even  weeks.  A  current  of  water,  or  other  fluid,  is  made  to  flow  continuously 
through  the  chamber  containing  the  object,  so  that  the  processes  of  respiration,  cir- 
culation, digestion  and  nutrition,  the  phenomena  of  inflammation,  and  the  effects  of 
some  classes  of  poisons,  may  be  studied  at  leisure  and  under  perfectly  natural  or 
entirely  controllable  conditions.  The  habits  of  life  of  small  aquatic  animals  are 
similarly  brought  within  reach  of  our  observations.  For  use  with  the  Magic  Lantern, 
in  projecting  the  images  of  living  objects  upon  the  screen,  this  apparatus  is  absolutely 
perfect  —  the  flow  of  fresh  water  through  the  chamber  being  so  constant  that  its 
inmates  are  entirely  free  from  inconvenience  during  the  most  protracted  exhibition. 

The  following  description  of  the  SYPHON  SLIDE  will  render  its  construction  and  use 
quite  clear.  In  a  slip  of  thick  plate  glass,  a  chamber  is  excavated  similar  to  that  in 
the  LIFE  SLIDE.  In  each  end  of  this  chamber  are  fine  perforations,  too  small  to 
permit  the  escape  of  the  animal  under  view,  but  sufficient  to  maintain  a  flow  of  water. 
These  openings  merge  into  tubular  mouths,  to  each  of  which  is  attached  a  tightly- 
fitting  elastic  tube  :  one  of  these  communicates  with  the  reservoir  of  water,  whilst 
the  other  acts  as  an  escape  conduit.  The  position  of  the  slide,  when  in  use,  must  be 
slightly  above  the  level  of  the  reservoir,  while  the  escape-tube  must  rest  below  the 
same,  thus  insuring  a  veritable  syphon  action  in  the  apparatus ;  a  constant  flow  of 
water  being  secured  in  connection  with  the  required  atmospheric  pressure  for  the 
retention  of  the  cover  on  the  slide.  It  is  not  necessary  to  have  bottles  specially  fitted 
for  use  with  this  apparatus ;  any  vessel  capable  of  holding  water  will  answer,  it  being 
only  necessary  to  insert  the  end  of  one  tube  in  the  reservoir,  and  by  gently  sucking 
at  the  end  of  the  other  establish  a  flow  of  the  water,  which  will  continue  so  long  as 
the  reservoir  contains  any.

neither  smell  nor  smoke.  One-twelfth  or  one-eighth  of  a  heavier  oil,  Sperm,  Lard 
or  Olive,  mixed  with  Kerosene,  makes  the  best  and  safest  oil. 

Testimonials  have  been  given  by  highest  authority,  as  to  its  safety  against  explo- 
sions. 

The  wick  should  be  trimmed  regularly.  If  a  crust  has  formed,  do  not  disturb  it, 
but  only  remove  any  little  point  or  unevenness  that  may  occur ;  do  not  use  the  scis- 
sors unless  the  wick,  through  uneven  draft,  should  have  coaled  or  charred  unevenly. 
By  this  method  you  will  have  an  even  flame,  and  the  wick  will  last  much  longer  than 
when  cut  frequently.  If  your  lamp  should  make  a  humming  noise,  which  is  caused 
by  the  shank  of  the  chimney  being  of  the  wrong  length,  raise  the  chimney  slightly, 
or  change  it  for  one  with  a  longer  shank. 

Use  kerosene  or  spirits  in  place  of  water  for  cleaning  chimneys.  The  brass  part 
of  the  lamp  may  be  cleaned  with  Vienna  lime  and  kerosene,  and  polished  with  rouge.

INTRODUCTORY  REMARKS  AND  EXPLANATIONS, 

Although  this  Catalogue  is  intended  as  a  guide  in  the  selection  and  purchase  of 
objects,  yet  it  is  obvious  that  no  such  list  can  be  strictly  correct  for  any  considerable 
time,  since  new  objects  are  being  added  continually,  and  the  vacancies  that  occur 
cannot  always  be  filled  instantly.  It  must  therefore  be  understood  that  these  object* 
can  be  supplied  on  demand  with  probability  rather  than  certainty ;  hence,  it  is  advis- 
able when  ordering  to  name  a  few  more  than  the  number  actually  required.  In  this- 
Catalogue  about  2,000  objects  are  comprised  ;  of  these  it  may  be  calculated  that  more 
than  one-half  will  be  found  in  stock.  Any  object  not  specially  named  will  be  pro- 
cured, if  possible,  when  ordered,  and  orders  are  solicited  for  any  object  desired,  even 
if  not  named  in  the  Catalogue,  as  it  is  our  aim  to  keep  and  supply  the  fullest  assort- 
ment of  Microscopic  Objects  to  be  found  in  this  country.  The  alphabetical  arrange- 
ment has  been  preserved  throughout,  as  the  easiest  guide  to  any  particular  specimen. 

The  prices  marked  on  the  top  of  each  page  have  a  general  signification  only  to  the 
objects  on  that  page,  and  refer  to  the  majority  that  follow.  Some  of  the  exceptions 
are  marked ;  but  the  prices  of  many  are  liable  to  fluctuation  from  scarcity  or  abund- 
ance, although  it  is  the  intention  to  adhere  as  closely  as  possible  to  the  general  list  of 
prices  herein  named. 

In  the  selection  of  these  specimens,  the  aim  has  not  been  so  much  to  reduce  the  pries 
as  it  has  to  improve  the  quality,  by  supplying  every  object  as  clean  and  perfect  as  its 
nature  will  admit.  The  predominant  wish  has  not  been  to  introduce  as  many  objects 
as  possible  in  each  department,  but  rather  to  rest  satisfied  with  such  as  are  the  most 
beautiful  as  natural  objects,  or  of  their  kind  the  best  illustration  of  special  structure 
or  function,  and  hence,  of  the  highest  interest  both  to  the  student  in  science  and  the 
popular  observer  also. 


JAMES  W.  QUEEN  &  CO.,  PHILADELPHIA  AND  NEW  YORK. 

Any  person  confidentially  known,  or  giving  reference  to  those  who  are,  if  he  desires 
to  purchase  a  reasonable  number  of  objects,  can  have  an  assortment  sent  for  exami- 
nation and  approval,  the  express  charge  both  ways  being  at  his  expense,  the  objects 
to  be  returned  within  one  tveek,  and  the  risk  of  damage  or  loss  in  transit  borne  by  the 
purchaser.  Such  specimens  are  sent  securely  packed  in  rack  boxes,  affording  facili- 
ties for  inspection,  as  well  as  for  packing  and  returning  those  not  chosen. 

In  this  Catalogue  will  be  found  many  objects  admirably  suited  to  educational  and 
instructional  use  for  the  elucidation  of  general  principles,  as  well  as  of  special  appli- 
cation and  adaptation.  In  Entomology,  the  various  parts  of  Insects;  in  Botany,  the 
Elementary  Tissues  of  Plants ;  in  Anatomy  and  Physiology,  the  organic  structure  in 
Man  and  the  lower  animals ;  the  Microscope  thereby  affords  the  parent  and  tutor  a 
pleasing  aid  to  the  communication  of  useful  and  truthful  knowledge.  It  would  be  a 
laborious  task  to  specify  those  objects  that  have  especial  interest  either  from  their 
novelty,  beauty  or  scarcity ;  but  there  are  many  that  may  repay  careful  notice  among 
the  Whole  Insects,  the  Transparent  Injections  and  Polariscope  Objects,  and  the  Mis- 
cellaneous Vegetable  Preparations. 

Special  attention  is  called  to  our  cheap  aeries  of  Educational  Objects  Nos.  1955 
and  1956,  which  fill  a  long  existing  want,  by  supplying  well  prepared  and  properly 
named  objects  to  students  and  others  at  a  low  price.  Their  excellence  is  apparent 
on  inspection.

MOLLEE'S  DIATOMAOEEN  TYPEN  PLATTE, 

1951.  Moller's  Diatomaceen  Typen  Platte,  No.  1,  is  a  slide  of  the  usual  size — three 
inches  by  one  inch  —  comprising  about  500  Diatoms  (correctly  392  distinct  species 
and  varieties),  being  acknowledged  types  of  Seventeen  Genera  of  the  Order  Diato- 
maccce.  The  shells  are  arranged  in  four  quadrangles,  each  formed  of  six  lines,  and 
each  line  containing  about  sixteen  species,  presenting  a  figure  of  the  following  form:

The  Diatoms  are  prepared  in  the  best  manner,  mounted  in  Balsam,  absolutely  pure 
and  clean,  while  the  integrity  of  each  and  the  symmetry  of  the  whole  may  be  said  to 
be  as  perfect  as  possible. 

Easy  reference  to  each  member  is  afforded  by  an  accompanying  Printed  Catalogue, 
by  which  the  name  of  any  individual  Diatom  on  the  slide  may  be  learned;  or  any 
name  in  the  Catalogue  as  easily  identified  with  its  corresponding  shell  on  the  slide. 

The  classification  is  that  of  Herrn  A.  Grunow,  of  Berndorf,  near  Wien. 

To  the  name  of  each  Diatom  is  appended  its  nature,  whether  fossil  or  recent.  Its 
origin,  whether  marine  or  from  brackish  or  fresh  water.  Its  geographical  locality, 
with  the  name  of  the  naturalist  who  assigned  its  nomenclature. 

On  the  whole  it  is  a  marvellous  production  of  human  skill  and  unceasing  persever- 
ance, a  wondrous  example  of  accurate  manipulation  and  delicacy  of  touch,  exciting 
the  admiration  of  all  who  see  it.  To  the  Naturalist  and  Student  it  forms  a  Cyclopae- 
dia of  reference,  which  may  be  long  and  repeatedly  studied,  with  untiring  interest 
and  returning  freshness.  It  is  worthy  of  a  place  in  the  cabinet  of  every  advanced 
Microscopist. 

The  price,  in  morocco  case,  with  bound  Catalogue,  is         ....     $40  00 

1952.  Moller's  Diatomaceen  Typen  Platte,  No.  2,  is  a  smaller  collection  of

plan  in  one  quadrangle,  accompanied  by  a  printed  Catalogue,  and 
quite  equal  in  quality  to  the  larger  collection.  The  price  of  this  is  16  00 

1953.  Moller's  Diatomaceen  Probe  Platte  is  a  collection  of  20  Diatoms,  by 

the  same  artist,  arranged  in  a  single  line,  on  a  slide  of  the  usual  size 
—  3x1  inch  —  and  graduated,  according  to  their  value  as  test  objects.

NOBERT'S  BANDS  OF  TEST  LINES, 

We  receive  direct  from  M.  Nobert,  of  Pomerania,  his  exquisitely  fine  Bands  of 
Lines,  ruled  on  glass,  as  described  in  a  communication  to  the  American  Naturalist, 
April,  1868,  reprinted  in  the  Quarterly  Journal  of  Microscopical  Science,  October,  1868, 
p.  131,  and  referred  to  in  Dr.  Carpenter's  Microscope  and  its  Revelations,  fourth  edi- 
tion, London,  1868,  p.  180.* 

The  latest  and  finest  of  M.  Nobert's  productions  consist  of  a  series  of  Bands  of 
Lines  from  No.  1  to  19,  the  distance  of  the  divisions  in  the  first  being  about  the 
11,000th  part  of  an  English  inch,  and  those  of  the  latter  the  112,000th  part  of  the 
same.  They  are  mounted  in  two  ways.  In  the  first,  price  $60,  the  lines  are  ruled 
on  a  slip  of  plate  glass,  protected  by  a  cover  of  thin  microscopic  glass.  The  more 
expensive  form,  price  $90,  has  its  lines  ruled  on  a  plate  of  microscopic  glass,  thick- 
ness -003,  and  covered  by  one  of  corresponding  size  and  thickness.  These  are 
mounted  on  a  slip  of  brass  3  inches  by  1  inch,  so  that  the  lines,  being  reversible, 
may  be  examined  on  either  side  under  an  achromatic  objective  of  one-fiftieth  of  an 
inch  focus.  This  form  has  the  advantage  of  admitting  the  close  approach  of  any 
achromatic  condenser  to  the  Lines,  and  at  the  same  time  facilitates  their  illumina- 
tion by  the  most  oblique  pencils  of  rays.  The  Lines  themselves  are  essentially  the 
same  at  $60  and  $90.

CHEAP  EDUCATIONAL  OBJECTS. 

The  uses  and  pleasure  of  a  Microscope  are  greatly  increased  by  having  at  hand  a 
collection  of  well-mounted  specimens,  since,  however  desirable  it  may  be  to  prepare 
one's  own  objects,  or  to  study  the  same  without  any  special  preparation,  it  follows 
that  there  are  thousands  of  highly  interesting  and  instructive  objects  which  cannot 
be  obtained  in  the  raw  state  (if  we  may  so  express  it)  by  every  one,  or  at  a  moment's 
notice,  when  needed.  The  unavoidably  high  price  of  the  finest  preparations  has 
long  been  a  serious  hindrance  to  many  who  would  gladly  possess  a  comprehensive 
collection,  but  find  the  cost  a  serious  tax  upon  their  pockets,  whilst  the  so-called 
cheap  objects  imported  from  Europe  are  of  such  an  utterly  worthless  character  as  to 
deter  them  from  purchasing,  even  at  the  low  prices  asked  for  the  same. 

In  order  to  meet  this  want,  we  some  years  since  introduced  our  "Cheap  Educa- 
tional" series  of  objects,  which  at  once  met  with  universal  favor,  and  the  demand 
for  which  has  steadily  grown  until  it  taxes  all  our  ability  to  meet  the  same.  These 
objects  are  prepared  and  mounted  under  the  immediate  supervision  of  our  Mr. 
Walmsley,  are  all  clean  and  excellent  specimens  of  their  various  classes,  embrace  an 
endless  variety  of  animal,  vegetable,  and  insect  subjects,  diatoms,  minerals,  metals, 
etc.,  and  are  guaranteed  to  be  correctly  named,  a  matter  of  great  importance  for 
educational  purposes.  The  Microscope  having  become  an  indispensable  adjunct  to 
every  well-regulated  school,  it  follows  that  the  specimens  shown  the  scholar  should 
be  good  and  reliable  ones. 

We  divide  these  objects  into  two  series  or  classes.  The  first,  or  School  Series,  are 
mounted  on  slides  measuring  2f  by  f  inches,  and  are  best  suited  to  the  smaller  and 
cheaper  kinds  of  Microscopes,  which  have  not  sufficient  stage  room  to  allow  of  the 
larger  slides  being  conveniently  used.  The  second,  or  Student's  Series,  are  mounted 
on  slides  measuring  3x1  inches,  the  same  size  as  the  most  expensive  objects.  This 
series  is  more  extended  in  variety  than  the  former,  containing  many  large  insect, 
vegetable,  polariscope,  and  opaque  specimens  which  cannot  be  mounted  on  the 
smaller  slides.  Both  series  are  covered  with  handsome  gilt  labels,  specimens  of 
which  may  be  found  on  page  70  of  this  Catalogue,  over  Nos.  1948  and  1949£.  The 
quality  of  the  specimens  is  the  same  in  both  series,  which  are  catalogued  as  follows :

rack  boxes,  containing  one  dozen  specimens,      .         .         .         .  $2  00

*  "The  mathematical  certainty  with  which  the  distance  of  these  lines  may  be  ascertained,  and  the  reg- 
ular gradation  of  the  series  they  present,  gives  to  M.  Nobert's  Test  Plate  a  very  high  value  for  the  deter- 
mination of  the  relative  merits  of  achromatic  objectives,  of  that  class  at  least  in  which  angular  aperture 
and  definition  are  of  the  first  importance." —  Carpenter  on  i?te  Microscope,  fourth  edition.

We  take  pleasure  in  announcing  that  we  have  recently  completed  arrangements 
•with  Dr.  J.  W.  S.  Arnold,  of  New  York,  by  which  we  shall  be  continually  supplied 
with  his  beautiful  preparations  of  Human  Anatomy,  including  opaque  and  transpar- 
ent injections,  preparations  of  the  eye,  brain  and  spinal  cord,  and  an  infinite  variety 
of  Pathological  preparations.  Our  Mr.  Walmsley  will  also  continue  to  furnish  his 
illustrations  of  Animal,  Vegetable,  and  Insect  Anatomy.  His  preparations  were 
awarded  the  highest  premium  (Medal  and  Diploma),  at  the  recent  Fair  of  the  American 
Institute,  New  York,  and  are  at  least  equal  to  any  imported. 

Mr.  Arthur  C.  Cole,  of  Liverpool,  England,  will  also  supply  us  with  his  exquisite 
slides  of  arranged  diatomaceae,  polycistina,  and  foraminifera,  which  are  quite  unique 
in  their  general  arrangement  and  finish.

NOTICE. 


Having  completed  arrangements  with  Messrs.  R.  &  J.  BECK,  whereby  Tre 
are  constituted  special  agents  for  the  sale  of  all  articles  of  their  manufacture  in 
the  United  States,  it  affords  us  pleasure  to  announce  to  our  friends  and  the 
public  generally,  that  we  have  now  in  stock,  and  shall  hereafter  keep  on  hand 
a  full  line  of  their  goods,  the  prices  of  which  are  the  same  as  those  in  London, 
United  States  duties  and  freight  charges  only  being  added.  These  goods  are 
specially  selected  for  our  sales,  and  are  guarantied  to  be  only  the  first  qualities 
of  their  respective  grades. 

Having  them  always  in  stock,  we  are  prepared  to  fill  orders  promptly,  thus 
avoiding  the  vexatious  delays  our  microscopists  have  so  long  been  obliged  to 
submit  to  in  obtaining  instruments  and  accessories.  If  it  is  desired,  however, 
to  import  any  article  specially,  we  can  do  so  at  the  shortest  notice ;  in  tljis  case 
a  pre-payment  of  one-half  the  amount  of  the  order  will  be  required. 

Under  the  New  Tariff  Act,  Institutions  of  Learning,  are  entitled  to  import 
scientific  instruments  free  of  duty.  We  are  prepared  to  receive  and  execute 
such  orders  very  promptly. 

It  is  unnecessary  for  us  to  say  aught  in  praise  of  the  instruments  manufac- 
tured by  this  eminent  firm,  whose  fame  is  world  wide.  We  would,  however, 
call  especial  attention  to  their  New  -^  Immersion  Object-Glass,  which,  in  every 
particular,  is  believed  to  be  superior  to  any  of  similar  power  heretofore  produced, 
whilst  its  price  is  but  little  more  than  half  those  of  other  makers.

FIRST-CLASS  MICROSCOPES. 


A  STAND,  of  similar  construction  to  those  in  this  class,  was  shown  by  R.  &  J.  B.  at 
the  Great  Exhibition  of  1851,  and  is  thus  mentioned  by  the  Jury  :  — 

"The  Stand  is  excellent  in  principle;  the  body,  stage,  and  appliances  beneath  are 
all  carried  on  one  stout  bar,  on  the  recommendation  of  Mr.  G.  Jackson,  by  means  of 
which  the  centring  of  the  achromatic  illumination  is  rendered  easy  and  certain ;  and 
on  any  tremor  being  communicated  to  the  instrument,  it  is  equally  distributed  over 
the  whole  of  the  working  parts."

GENERAL    REMARKS. 


The  difference  in  the  price  of  "  First-class  Microscopes"  as  numbered  in  this  Cata- 
logue, is  dependent  upon  the  number  of  Object- Glasses  and  the  amount  of  Apparatus 
supplied,  the  quality  being  the  same  throughout. 

The  Eye-pieces  should  be  frequently  wiped  with  a  clean  cambric  handkerchief,  or  a 
piece  of  soft  wash  leather.  The  Object- Glasses  should  never  be  touched,  except  by 
the  makers. 

Full  instructions,  as  to  the  best  mode  of  using  all  the  foregoing  instruments,  are 
given  in  Richard  Beck's  Treatise  on  the  Construction,  Proper  Use  and  Capabilities  of 
R.  &  J.  Beck's  Achromatic  Microscopes.  Royal  8vo,  with  27  plates.  Price,  $8.  75.
